The Chairman said it was his painful duty to announce that since 

 their last meeting, the death had occurred of one of their number, who 

 during almost the whole of his life had been held in the highest 

 esteem and respect by all microscopists. He referred to Mr. Hugh 

 Powell, of the firm of Powell and Lealand. It was truly a ripe old 

 age to which he had attained, but nevertheless it was always painful 

 when at length the time of parting came, and both as a Society and 

 as individuals, he was sure they must deeply regret the removal of one 

 whom they had always held in such respect. It was by an unfor- 

 tunate coincidence that it fell to his lot to announce to the same 

 meeting the death of Mr. Powell's most distinguished rival in 

 America, Mr. E. B. ToUes, of Boston, who had also done so much for 

 the improvement of objectives. Peace be to both of them, with the 

 kindliest feelings of sympathy towards their respective families, of 

 every Fellow of the Society. 



Mr. Crisp exhibited (1) Mr. H. P. Aylward's Microscope, having 

 a swinging tail-piece rotating completely round the stage, so that the 

 mirror and substage could be set in any required azimuth (p. 110) ; 

 (2) a Microscope by Mr. A. McLaren, rotating upon the horse-shoe 

 foot, so as to secure greater stability for the instrument when the body 

 was inclined at any considerable angle (p. Ill) ; (3) a Microscope by 

 Herr F. W. Scbieck (p. 112), with a number of objects inserted in 

 the circumference of a revolving drum, so that each could be passed 

 in turn beneath the objective. A translation of the inventor's de- 

 scription of the instrument and its advantages was read to the 



Ser. 2.— Vol. IV. M
